GRAiN-HEADER.

SPECIFICATION forming part of Letters Patent No. 391,383, dated October16, 1888.

Application filed April 16, 1888.

To ail whom. it may concern.-

Be it known that I, SAMUEL J. MYRIoK, a citizen of the United States,residing at Helix, in the county of Umatilla and State of Oregon, haveinvented a new and useful Improvement in Grain-Headers, of which thefollowing is a specification.

Hy invention relates to improvements in grain-headers; and it consistsincertain novel features, hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side view of my improvedmachine. Fig. 2 is a plan view of the same. Fig. 3 is a centrallongitudinal section. Fig. 4 is a detail perspective view of theconnection between the reciprocating lever and the cuttenbar. Fig. 5 isa detail section of the same.

teferring to the drawings by letter, A designates the main rectangularframe composed of suitable longitudinal bars, 0, and transverse bars d,securely fastened together and having theaxlesB journaled in suitablebearing-boxes f, secured to the longitudinal side bars of the frame. Thespecific construction of the main frame, however, is not an essentialelement of my invention, and a detailed description there of isconsidered unnecessary. The driving and supporting wheels 0 are mountedon the axles B, and one of the axles is extended to one side of theframe A and has a gear'wheel, D, mounted on said extended portion. Alongitudinal shaft, E, is journaled in suitable projections, F, on theside of the frame, and is provided at its rear end with a pinion, G,meshing with the gear-wheel D, and at its front end with a crank-disk,I. This crank-disk is connected, through a pitman, J, with areciprocating lever, K, having its rear end pivoted to the rearcross-bar of the frame and its front end connected to the cutter-bar.The outer end of the pitman J is connected to the crankdisk by asuitable wrist-pin, and its inner end is connected to the lever K bybeing pivoted between two lugs or offsets, g, on the top side of saidlever. The front end of this lever plays in a longitudinal slot, L, inthe front cross-bar of the frame, and to the said front end of the leverI secure an angle-plate, M, which projects through the slot L and hasthe front upwardly-projecting end N provided with aver Serial No.270,787. (No model.)

tieal slot or perforation, O, which is engaged by a projection, P, onthe rear edge of the cutterbar Q.

R designates the finger-bar, consisting of two parallel plates, h h,secured to and projecting from the front cross-bar ofthe frame, andhaving the guard-fingers S projecting forward therefrom. The lower plateis composed of angleiron, as shown, the guard-fingers being secured tothe forwardly-projecting horizontal flange of the same. The plates h hof the finger-bar are provided with longitudinal slots T, to permitmovement of the angle-plate M, and these slots or openings are coveredby a plate, U, secured to the top plate to prevent the collection ofdirt in the openings, and consequently choking and clogging of theworking parts. This plate U is peaked or made to taper downward towardits edges, as most clearly shown in Figs. 2 and 5, thereby providingroom for the play of the upper end of the angle-plate M. The front edgeof the upper plate It is provided with shoulders V, between which playsa rib or flange, \V, secured to the upper side of the cutter-bar. Thisrib or flange, by contacting with the shoulders V, limits the play ofthe cutter-bar,as will be readily understood.

The finger-bar is not secured rigidly to the front bar of the frame, butis hinged thereto, as shown, by means of hinges i. To the lower edge ofthe depending flange X of the lower plate h are secured, by means ofhinges j, the front ends of the links or connecting-bars Y. These linksor connecting-bars pass backward through suitable guides, Z, on theframe A, and have their rear ends hinged at to the lower edge of thecross-head a of the tongue I). The upper edge of this cross-head isconnected by hinges c to the rear cross-bar of the frame, as shown. Avertically-adjustable steeringwheel, (2, is mounted in the rear end ofthe tongue.

A transverse carryingbelt of the usual or any preferred construction isarranged in rear of the cutter-bar, and is mounted on thelongitudinally-arranged rollers Z. This belt receives the out grain andcarries it to a wagon drawn along by the side of the header. Thiscarrying-belt is well known in the art, and forms no part of myinvention, and for the sake of clearness in the illustration of theessential features of myinvention I have omitted the mechanism foroperating the belt.

In use the draft animals are hitched to the tongue and driven over thefield in the usual manner. As the machine is pushed forward over thegrain, the driving-wheels are rotated and the motion of the same iscommunicated to the reciprocating lever, as will be readily understood,through the medium of the gearwheels, crank-disk, and pitman. The leverbeing connected to the cutter-bar, the same will be reciprocated and thegrain will be cut.

It will be observed that, as the cutter-bar is hinged to the front endof the main frame, it will have a limited play, and will readilyaccommodate itself to the unevenness of the ground. The angle formed bythe cutter-bar and the front end of the main frame can be readily variedby manipulating the tongue. By adjusting the steering-wheel so as toelevate the rear end of the tongue the lower edge of the cross-head willbe drawn rearward and pulling on the links or connecting-bars willdepress the cutter-bar. On depressing therear end of the tongue thecutter-bar will be raised. It will thus be seen that the cutter-bar willbe maintained in a horizontal position at all times, so as to cut thegrain squarely, and can be readily adjusted to the height of the grain.

The cutting apparatus being arranged close to the carrying-belt, the cutgrain will fall directly onto said belt, and will thus be prevented fromaccumulating on the cutter-bar and clogging the same. The connectionbetween the cutter-bar and the pitman will permit the cutter-bar tomaintain its horizontal position while the main frame is being raised orlowered.

Having thus described my in vention, what I claim, and desire to secureby Letters Patent,

1. In a grain-header, the combination of the main frame, the finger-barhinged at its top edge to the front end of the said frame, the tonguealso hinged at its upper edge to the rear end of the same, and the linkshaving their front and rear ends hinged, respectively, to the lower edgeof the fingerbar and the corresponding edge of the tongue, as set forth.

2. The combination,with the main frame, of the fingerbar hinged atitstop edge to the front end of said frame, the tongue also hinged at itsupper edge'to the rear end of the frame, guides secured to the underside of the main frame, and the links passing through said guides andhaving their opposite ends hinged, respectively, to the lower edge ofthe finger-bar and the corresponding edge of the tongue, as set forth.

3. The combinatiomwith the main frame, of

the lever pivoted thereon, mechanism for reciprocating said lever, thefinger-bar hinged to the front end of the main frame and provided with alongitudinal slot, T, and having shoulders V in its front edge, thecutter-bar supported by the finger-bar and provided with a rearwardprojection, P, and having a longitudinal rib on its upper side playingbetween the shoulders V, a plate covering the slot T in the finger-bar,and a perforated angle-plate secured to the reciprocating lever andengaged by the projection P, as set forth.

In testimony that Iclaim the foregoing as my own I have hereto affixedmy siguatu re in presence of two witnesses.
